invented new and useful Improvements in Sofa-Beds, &c., of which the following is a specification.

This invention relates, particularly, to combined sofas and beds, or combined couches and beds, and the primary object is to provide a device of improved construction and operation.

The invention is illustrated in its preferred embodiment in the accompanying drawings, in which- Figure 1 represents an Aend view of the improved structure in unfolded condition, one of the end-standards being removed, and a rear frame member employed being shown in section; Fig. 2, an enlarged broken horizontal sectional view, taken as indicated at line 2 of Fig. 1, illustrating the means whereby the seat is revolubly mounted in the frame; Fig. 3, a broken vertical section, taken as indicated at line 3 of Fig. 1; Fig. 4, a view similar to Fig. 1 but showing the structure in sofa form; ig. 5, a broken sectional view, taken as indicated at line 5 of Fig. 7; Fig. 6, a similar View, showing the bed-frame in folded condition; Fig. 7, a broken horizontal sectional View, taken as indicated at line 7 of Fig. 1; Fig. 8, a broken vertical sectional view, taken as indicated at line 8 of Fig. 1; Fig. 9, a broken sectional view similar to Fig. 5, but, showing a modification of the truss-controlling device; and Fig. 10, a broken sectional view, similar to Fig. 6, but showing the modification shown in Fig. 9..

Referring to Figs. 1 to 8, inclusive, the

referred embodiment comprises a frame A iiavin end-standards A1, which provide the arms or the sofa, and having a longitudinal rear frame member A2 detachably connected with the end-standards; a swin ingly-mounted back B, whose lower edge is normally locked over the rear ortion of the seat, the back bein capable o movement to permit reversal o the seat; a seat C reversibly mounted in an improved manner in the frame A; and an improved folding bed D, carried in the lower portion of the seatframe and normally housed beneath the seat when the structure 4is in sofa form,

' struction.

The frame A may be of any suitable con- In the construction illustrated, the end-standards A1 may be made as ornamental as desired. The lower rear connecting member A2 is equipped with attaching devices 1, having hook-portions which detachably engage screws, or studs, 2, secured tp the end-standards.

The back B is connected by hinges, or iiexible strips, 3, with an upper rear frame member 1, which may be detachably connected, in any suitable manner, to extensions 5 of the end-standards A1. The back B is provided near one of its hinges with a clip lower end is provided with a stud 8, which engages a slot 9 in a member 10 attached to an end-standard. The slot 9 has an oH-set, or recess, 9a at its upper portion, which may be engaged by the stud 8 when the back is to be held in an elevated position.

The seat C comprises a frame, having end members 11, a front connecting member 12, a rear connecting member 13, and braces 14 joining the members 12 and 13; and a cushion 15, which may be provided with the usual upholsterinr springs (not shown).

The mounting for the seat C comprises a pair of frame-carried plates 16, applied to the inner surfaces of the end-standards A1; and a pair of seat-attached plates 17 secured to the end members`11 of the seat-frame, and equipped with studs, or rollers, 17, 17h, which Work in cam-slots 161, 16", with which the plates 16 are provided.

As appears from Figs. 2 and 3, the plates 16 are separated from the inner surfaces of the end-standards A1 by spaces 18. This is preferably accomplished by providin the plates 16 with outwardly-struck per orate bosses 19, which accommodate screws 20, which serve to secure the plates to the endstandards. The rollers 171 and 17" are attached to the plates 17 by pivot-studs 21, and the rollers have flanges 22 which 'are confined between the plates 16 and the endby the arrow in Fig. 4, the back being first swung out of the way. In reversing the seat,

the roller 1711 travels in the vertical slot 161,

which bisects the horizontal slot 16a, while the roller 17b travels on the lower wall of the slot 16a. In both the u right and inverted positions, the rollers 1%* and 17b rest upon the bottom walls of the slots 16, thus holding the seat in stable condition. This construction, While providing for the easy reversibility of the seat, renders unnecessary the use of catches or locking devices for holding the seat in either the normal upright position or the inverted position.

The folding-bedB preferably comprises a. section 23 ixedly secured to the bottom portion of the seat-frame and constituting a rear bed-section; and a section 24 having hinge-connections with the section 23 an constituting a front bed-section.

rllhe section 23 is U-shaped and comprises a longitudinal member 23L and end-members 23h. To the extremities of the members 23b are securely attached hangers, or hingemembers, 23,'which, when the structure is in sofa-form, depend from the rear corners of the sofa-seat. The section 24 'is U-shaped and comprises a longitudinal member 24a, and end-members,l24b. The extremities of the arms, or members, 24", have rigidly secured thereto short arms,or hinge-members 24, the extremities of which are connected with the hinge-members 23C, by pivots 25. The extremities of the end-members 23 afford shoulders 26; and the extremities of the end-members 24"' al'ord shoulders 27 l( Fig. 6), which abut against the shoulders 26 vwhen the bed is extended.

The end-memberg of the section 24 have pivotally connected therewith legs 28, which are joined by links 29 to pivots 30 carried by ears 31, with which the hinge-members, or hangers, 23, are provided. The arrange- -ment is such that the legs will be automatically folded and unfolded in the operations a, of folding and opening the bed, respectively.

At the joint between the sections of the bed-frame is disposed a U-shaped truss 32. The extremities of this member are preferably joined, by pivotal connections 33, to t e extremities of the end-members 24b of the front bed-section. The longitudinal por tion of the trussmember,is connected, by links 34, tothe seat-frame. In the illustration givenY the links 34 are pivotally connected wit. cli s 35 carried by the bracemembers 14, an are loosely joined by a pin 36v to the central portion of the truss-rod. It will be noted that the truss-rod 32 is elevated from the position shown in Fig.`5 to the position shown in Fig. 6 when the bedframe is folded. The links .34 permit this movement, but serve at all timesto keep the .truss-rod substantially within the cones rod will,

of t seat-frame, so that the t vfixedlyv secured to the lower meneer not get out of position when the seat is v swung to the normal upright position shown in Fig. 4. The bed-frame is maintained in the folded condition by a catch 37 carried by the member 12 of the seat-frame. The catch 37 may be of the usual construction, being capable of turning in a bearing 38 applied to the member 12.

The folding-bed frame is equipped with the usual iexible wire mattress, or spring bed-bottom 39.-

It will be noted from Fig. 4 that the cushion 15 of the seat is disposed mainly in front of the longitudinal `seat frame member 13, and it will be understood that where upholstering springs are 'employed' they will be disposed in front of the trussrod 32, so as not to interfere with the operation of the truss-rod.

When it is desired to convert the struc -ture from sofa-form to bed-form, the sofa 28 are extended. By providing the bed-sections 23 and 24 with either arms, or oH-set 95 hinge-members, 23, and .24, a simple construction is aorded; and room is provided, in the folded condition of the bed, for the bedding, which, as is usual in this class of construction, is folded in the operation of folding the bed.

After the bed is opened, the back B may be lowered to rest against the member 12.

The construction described is simple, cheap, durable and capable of being operated with the greatest facilit The foregoing detailed description has been given for clearness of understanding only, and no unnecessary limitation shoul be understood therefrom, but the appended claims should be construed as broadly as permissible, in view of the p rior art.

What we regard as new, and desire to secure by Letters Patent, is-

1. In a structure of the character set forth, the combination ofl a frame, a seat reversibly mounted therein, a bed-section portion of the seat-frame, han ers de ending from the rear corners of te seatame, a bed-section having upwardly-extendin membersI pivotally connected with said angers, (a truss pivotally connected with said second-named ed-section near the `points of connection with said hangers, and connecting means between the seat frame d truss for maintainingthe truss in properly housed position. v

2. En a structure of the character set n forth, theccmbination of a frame, a reveiiso bly mounted seat, a rear bed-section fixedly secured to the lower portion of the seatframe, hangers depending from said bedsection, a front bed-section equipped With upwardly-extending arms pivotally connected with said hangers, a truss pivotally connected with the extremities of the endmembers of said front bed-section, and connecting means between said truss and seat frame for maintaining the truss in properly 10 housed position.
